DD was a surprisingly well-mannered eater until a couple of months ago, when she had a cold for ages and got into the habit of eating with her mouth open. Even after her nose unblocked, she still eats with her mouth open, smacking away. I have a genuine horror of noisy eating, though - I've tried being patient and gently reminding her to chew with her mouth closed, because, well, she's 3! But it's still just as bad, and I feel like I can't even be in the same room as her when she's eating, the sound upsets me so much.
I don't want to give her some kind of complex about eating, so does anyone have any good advice, beyond reminding her every 20 seconds at the dinner table?
